All these properties combine to make this material the most machinable of all common carbon and alloy steels. This machinability can be evaluated in terms of low cutting forces and good chip breaking characteristics. Material 12L14 Steel Properties 12L14 material density is 7.87 g/cm³ (0.284 lb/in³); Tensile strength is 390 MPa (57 ksi) for hot rolled， aerospace and other fields. The lower carbon content of 12L14 steel， resulting in breakable chips.
